Alcoa shares emissions data, various updates

The Community Advisory Panel to Alcoa -Rockdale Operations (CAPARO) received its annual report on Rockdale Operations’ emissions when the community members met with Alcoa in November. In addition to the written environmental and safety updates, Alcoa provided information on several subjects members find of community interest.

Terry Blodgett, Environmental and Industrial Health Manager, reported that air emissions data submitted annually to the Texas Commission on Environmental Quality (TCEQ) come from the atomizer process and the natural gas fired furnaces that melt the aluminum used to make the powdered product.

Emissions of aluminum dust totaled 130 tons in 2011 and are accounted for in the EPA Toxics Release Inventory (TRI). Combustion of natural gas produced 22 tons of nitrogen oxides, 12 tons of carbon monoxide and two tons of volatile organic compounds. Drums of unusable aluminum powder, which are disposed of in a registered on-site landfill, totaled 91,000 lbs. in 2011. The powder is disposed if it does not meet customer specifications and cannot be recycled. There were no TRI releases to water in 2011.

Blodgett showed photos of the construction of new flood gates for the Alcoa Lake Treatment System. The dam has an emergency action plan, as required by TCEQ.

Members learned that due diligence is underway with no final decision about Lower Colorado River Authority (LCRA) purchase of the Alcoa property.

Alcoa’s Public Affairs and Safety Manager, Jim Hodson, also responded to questions about Sandow reclamation, Alcoa’s Ten Million Trees program, a corporate biodiversity survey, landfills, corporate information, and Alcoa’s application to the Post Oak Savannah Groundwater Conservation District for additional groundwater withdrawal and wells.

CAPARO will meet on Monday, March 11 for an update from Alcoa. The 6-8:30 p.m. meeting will be at the Alcoa Lake Training Center in Rockdale. Details will be published closer to the meeting date. For more information, contact the CAPARO facilitator at 800-484-9212 code 4127.

Rockdale residents are also welcome to contact CAP members John Hughes at 512-947-3191 or Bob Wilson at 512-446-5700.
